Elasticsearch 0.90.1 Released

The Elasticsearch dev team are pleased to announce the release of Elasticsearch 0.90.1, which is based on Lucene 4.3. You can download it here.

We highly recommend upgrading to 0.90.1 from 0.90.0 as this release includes some key bug fixes, notably a fix to the bool filter which could produce incorrect results (#2979) and a fix to the DFS search types (#3012).

Besides the bug fixes, 0.90.1 also has some nice new features and enhancements, especially:

New APIs for aliases, including the ability to retrieve specific aliases more efficiently (#3075, #3076, #3077 , #3100)
